Tuple assignment error produces two error messages, whereof one is not right

[Peter Aronsson]

The following model:

{{{model Model1

Real[3] x;

Real y;

function test

input Real x;

input Real x2;

output Real y[3];

output Real z;

algorithm

y:={x,x2 + 1,x + 2};

z:=x2^2;

end test;

algorithm

(y,x):=test(time, time^2);

end Model1;}}}

produces the following error messages:

Error processing file: model1.mo
[model1.mo:15:3-15:28:writable] Error: Type mismatch in assignment in (y,x) := M
odel1.test(time,time ^ 2.0) of (Real, Real[3]) := (Real[3], Real)

{{{[model1.mo:15:3-15:28:writable] Error: Tuple assignment only allowed when rhs is

function call (in Model1.test(time,time ^2.0))

Error: Error occurred while flattening model Model1}}}

Clearly, the second error is not true, and it should not be printed. This is a common type of mistake in the compiler that probably originates from the fail semantics of RML combined with unsufficient programming logic ;-)
